Abstract (en)
Device generating electrical disturbances in the grid connected to a system for generating electrical energy, such as a wind turbine or a solar plant, in order to test the response of generators to disturbances in the grid, disturbances being understood as voltage dips, voltage surges, phase jumps and frequency changes, which comprises a three-phase transformer or three single-phase transformers having variable taps connected in series between the collector system and the generator, said transformer being responsible for producing voltage surges, voltage dips and phase jumps by means of the switching of a bypass branch with an impedance with the branch that contains the transformer, there likewise being a battery of capacitors arranged in parallel for producing voltage surges with the aid of series impedance and/or resistance. In addition, there is a reducer transformer arranged in parallel, which is connected to a rectifier, and the latter is connected to resistances for testing the response to frequency variations.
